You cannot be beaten at anything, until you quit in your own mind. There is no defeat except from within. You have no really insurmountable barrier except your own inherent weakness of purpose. Consider yourself on a very long journey. Sustain your personal vision of success. In the end, you can only fail if you do not try. Winning isn't everything, but wanting to is. If you've got the nerve to make it, you will. There is no failure except in no longer trying. Success is a road paved with perseverance.
